New Heating Boiler for Waiouru Military Camp Meets Emission Standards

The NZ Defence Force (NZDF) commissioned, 8MW, $3.8 million new heating boiler for the Army’s Waiouru Training Camp, was formally handed over at a function at the Camp today. This was the first stage of upgrading the heating system at the Waiouru Camp.

Following the updating of the regulations to meet higher emission standards, the NZDF took the opportunity to install a new, much larger boiler to replace two older inefficient coal fired boilers that were struggling to meet the heating demands of the Waiouru Military Camp.

“The new boiler has replaced two much older boilers which were structurally failing and were quite dirty in respect of discharge of emissions into the environment,” says Principal Mechanical Engineering consultant, Gavin Dunn of global consultancy, Opus International Consultants.

“The new boiler operates on a much cheaper grade of coal - and this will reduce the operating cost and is significantly more efficient than the two older boilers. It provides heating and water heating to 70 buildings in the Camp and also provides heating for the swimming pool. “

The new boiler is a high efficiency ‘Maxitherm’ water-tube configured boiler with a louvre travelling grate. It was almost entirely built in New Zealand, including the casting and machining of specialised components and the writing of soft ware.

The upgrade of the boiler also required alterations to the existing boiler house and included the installation of a taller flue stack which will help to ensure the new standards for air emissions are achieved.

The boiler installation and the new foundations were designed by Opus International Consultants, who also provided the contract management for the construction and installation for the NZDF Joint Logistics and Support Organisation Property Group. The boiler was constructed by Lyttelton Engineering of Christchurch, who was able to build and install the boiler within a very tight timeframe.
